Fixes https://github.com/googlefonts/ufo2ft/issues/485

For the tests to pass we need to release fonttools with https://github.com/fonttools/fonttools/pull/2860

I hope this will also fix another issue related to building fonts with huge glyph set like Source Han Sans, in which compiling post format 2 raises overflow error, but the compilation step is unnecessary and can be delayed at the very end after the postcript glyph names have been dropped (post format 3), like I do in this PR.
